An experienced commercial vehicle attorney can help you determine the cause of your accident and help you seek appropriate compensation. This list may not reflect recent changes (learn more). The data, in fact, shows that for GA aircraft weighing 12,500 pounds or less, the problem of mechanical or maintenance failure due to age is actually declining. The two major concepts that are talked about in the Air Detective Tips are the 5M and the Shell concepts. A component on a plane may be unsafe by design or may not have been properly maintained and lead to a sudden failure that can injure or kill those onboard. The Transportation Safety Board of Canada recently issued a report on the forced landing of a 1942 Douglas DC-3 C-GWIR after an engine failure on 19 August 2013.The Buffalo Airways aircraft was operating a scheduled passenger flight between Yellowknife and Hay River within the Northwest Territories. Typically, the failure stems from inadequate maintenance or faulty parts. Investigators suggested earlier that bad weather could have been the primary cause, but now they say that if the crash wasn't caused by a mechanical failure, it … Whether due to vehicle negligence, normal wear and tear, or a fault in the part, these unexpected failures can cause even the best driver to get into a crash. For me it is easier to read about an accident when no one is necessarily at fault and it is simple mechanical failure. Faulty equipment accounts for approximately 15-20 percent of aircraft crashes. Aircraft mechanical failure can be defined as a failure or break down in a mechanical aircraft component due to that component reaching the extent of its "age" or improper install or application. As aircraft have become more reliable, the proportion of crashes caused by pilot error has increased and now stands at around 50%. There were many thousands more wrecks and deaths overseas. Vehicle recalls are common. Lightning strikes can cause complete electrical failure to a plane. The GAJSC has produced several safety enhancements related to weather as part of their work on loss of control in flight.
